"¿Sabes leer chino?"
Translation:Do you know how to read Chinese?
Because saber means 'to know how to'. Your sentence would be ¿Lees chino?
I agree that "Do you read Chinese?" can be idiomatic for "Do you (know how to) read Chinese?" so please report it. Just understand that the reverse, ¿Lees chino? is not the correct way to ask it in Spanish.
